FAST LIGHT-PROOF COLORING MATTERS OR DYES AND PROCESS OF MAKING SAME.

No Drawing.

certain new and useful Improvements in Fast Light-.lroof oloring lvlatters or Dyes and Processes of Making Same, of which the following is a specification.

This invention relates to improvements in the manufacture of fast light-proof dyes or coloring matters.

In the utilization of dyes or colors for any desired purpose, whether painting, dyeing of fabrics or printing, it is essential that the colors should resist the action of light and be unaffected by treatment with water, soap and like materials, such as are used for cleaning the fabrics, and also that it should be possible to prevent them from becoming mixed together or diffusing into one another, either at the same time as, or after, they are put on. The latter is of special importance when the colors are to be put on side by side, as for example in a printing process.

According to this invention a process for the manufacture of fast coloring matters of a light resisting nature consists in forming a colloidal solution of the coloring matter in a mass having a base of alizarin (Turkey red) oil and insoluble in water, the mixture of coloring matter and material with which it is to be incorporated being heated until the whole solidifies o cooling. This mass in which the pigment is dissolved sets to a homogeneous translucent or transparent amorphous substance and serves as a color carrier or vehicle which enables the pigment to spread over the surfaces to be painted. Moreover the cOlor vehicle protects the pigment owing to this latter being embedded or dissolved therein; for the same reason coloring matters manufactured in this manner are especially suitable for color printing, as the surface from which the impression is to be taken is simply coated with a layer of the coloring matter. and on moistening this with a solvent for the color carrier, the latter, together with the pigment dissolved therein, is removed in a larger orsmaller quantity according to the amount of solvent employed. The mixture of a color pigment in alizarin oil may be used for some purposes. without other ingredients. but I prefer to add thereto other carrier- Specification of Letters Patent.

forming and filling materials, as hereinafter described.

A further feature of this invention consists in incorporating with the color pigment and alizarin oil, either salts of metals of the alkali earths or alkalis or basic aluminium acetate, or mixtures of these substances. Naphthalene and also certain fats and oils containing substances like trimethylamin, cholesterin or triglycerids can also be incorporated with the mixture in which the coloring matter is dissolved according to the particular use for which the composition ultimately obtained is intended.

In carrying out this invention, as carriers for the pigment there have proved particularly advantageous substances obtained by heating together alizarin (Turkey red) oil and salts of metals of the alkali earths or alkalis with or without basic aluminium acetate. Particularly good results are obtained with carriers produced by heating mixtures which contain in addition to alizarin (Turkey red) oil, .basic aluminium acetate, Most salts of metals of the alkali earths however, and some alkali metal salts, are also suitable for the purpose.

Throughout this specification and claims the term metallic salts does not include salts other than basic aluminium acetate and salts of the alkali and alkali earth metals, and the term alizarin (Turkey red) oil is used to denote neutralized products obtained by treating with sulfuric acid not only olive oil, but also other oils, such for example as castor oil, cotton seed oil and other oils containing glycerids of palmitic acid, oleic acid, etc. By incorporation of pigments in such carriers in which they are completely dissolved, there are produced dye-stufls or colors possessing a much greater resistance to light than that Which the same pigment would have if it were not incorporated in this way in the carrier mentioned above. In addition to the substances already mentioned as used for forming the pigment carriers, namely alizarin (Turkey red) oil and salts of metals of the alkali earths or alkalis. there may be added to the mass other substances, partly for the purpose of increasing theresistance of the color to light, and partly as more or less indifferent substances chiefly intended for insuring better distribution of the pigment in the mass of a its carrier. The substances of the first mentioned kind include naphthalene and its derivatives. It has been found that when a mixture containing alizarin (Turkey red) oil and a salt of an alkali earth metal is heated in the presence of naphthalene, the resistance to light of the color obtained with the use of such carrier is rendered still greater than the resistance which the color in question possessed when naphthalene was not employed. More especially is this the case when the carrier contains basic aluminium acetate. The same effect as naphthalene is produced by the majorityof its derivatives, and throughout this specification and claims the word naphthalene is used to denote both naphthalene or its derivatives. Further, an addition of oils and such animal fats which contain .tri-methylamin, cholesterin or tri-glycerids, such as tri-butyrin, tri-olein, and tri-palmitin, has also proved of great assistance in improving the resistance to light of the coloring matters, and throughout this specification and claims substances such as the oils and fats mentioned above will be denoted by the term animal fatty substances.

The favorable action of the animal fatty substances employed, such as fish oil, wool that the naphthalene be added thereto while the mass is hot and in the presence of animal fatty substances, such as fish oil or wool fat and vegetable resins, as for instance copal resin.

In order to dilute the coloring matters obtained in the manner described to the degree required for their practicable application it is advisable to use as diluents varnishes of a special nature, namely, those produced by heating together resin and fish oil and dis solving the product in naphtha or in liquids obtained by the distillation of resin, coal or naphtha, such for example as turpentine oil,

toluol, benzol and creosote.

The following are examples of preferred methods of carrying the invention into effeet: 1

E wample -l--M anufacture of colors for 01'- dinam painting purposes.There lare first of all prepared three mixtures consisting of1. 100 gms. basic aluminium acetate and 600 gms. alizarin (Turkey red) oil. 2. 10

'gms. Biebrich scarlet of the class of azo dyes and 100 gms. alizarin (Turkey red) oil.

3. 30 gms. naphthalene and gms. fish (train) oil. These three mixtures are combined together, and into the same are introduced 40 gms. talc, 30 gms. powdered clay and 30 gms. pulverized barium sulfate, and

the whole mass is heated with constant stiras transparent as glass and is colored in a perfectly uniform manner. A suitable diluent or varnish for the coloring substance is obtained by stirring and boiling together 2.5 kg. fish (train) oil with about 9 kg.

shellac or, as is preferred, with 7.5 kg. powdered copal resin (Angola) and a small quantity, for instance 1 kg. turpentine oil, the mass being thereupon poured while still warm into about 30 kg. toluol or 10 kg. turpentine oil and thoroughly stirred, until a clear solution is produced. Into this varnish is introduced a suitable quantity of the coloring matter obtained in the above described manner, until' the desired degree of spreading and covering capacity is obtained.

Example Il-Oolors for artistic painting.-For artistic painting there can be used the same coloring matter as that just described, but preferably with a slightly different varnish. This varnish differs from the varnish described for colors intended for ordinary painting, only by the fact that the solid resins are partly replaced by easily liquefied resins in the shape of balsams, such as for example copaiba balsam, in such manner that for 2.5 kg. fish (train) oil there are used 5 kg. copal resin and 2.5 kg. copaiba balsam. These three ingredients are again boiled together, whereupon the mass is again dissolved in a suitable quantity of toluol or some other product of distillation of naphtha, coal or resin.

'Ewample II[00'Z0rs for printing purposea-First of all there are prepared three mixtures, as before consisting of :1. 100 gms. basic aluminium acetate and 200 gms.

alizarin (Turkey red) oil. 2. 10 gms. Biebrich scarlet and 100 gms. alizarin (Turkey red) oil. 3. 20 gms. naphthalene and 20 gms. fish-(train) oil. These three mixtures are combined together, and a mixture of resins, consisting of 50 gms. Canada balsam, 250 gms. Venetian turpentine, 100 gms. copal resin, 50 gms. pine resin, 25 gms. elemi resin, 50 gms. shellac, is added to it, with constant stirring and heating. Moreover, 25 gms. glucose, previously mixed if desired with powdered resins, are added to the mass. The mass is again boiled, until it becomes solid on cooling. With this coloring mass is combined a thick fluid resin mixture previously prepared by mixing 125 gms. fish (train) oil, 650 gms. copal resin with 225 gms. spirits of wine (95%) or some other (preliminary) solvent, and boiling the mixture in question. In the event of the mass being too solid for treatment, some solvent, such as for instance toluol, can be added to it, until it acquires the desired consistency.

The above mentioned proportions of the substances employed for the production of coloring matters may vary within Wide limits, and must be altered to suit the nature of the coloring matter or dye stuff used, and of the salts and other admixtures (naphthalene or animal fatty substances) to be combined with the alizarin (Turkey red) oil in the production of the pigment carrier. It is to be understood therefore that the proportions for the mixture mentioned in this specification are only given by way of example, and that these can be varied according to the particular coloring matter that is to be produced without departing from the spirit and scope of the invention. I also desire it to be understood that the appended claims are to be read with the aforegoing statements in view.

The process can be applied to any available pigments, in so far as they are soluble, or can be distributed colloidally (not in the form of grains), in a carrier substance produced from alizarin (Turkey red) oil and basic aluminium acetate, and/or a salt of an alkali earth or alkali metal, the pigments, if desired, being previously dissolved in a small quantity of a solvent other than alizarin oil for the purpose of facilitating their introduction into the carrier substance. As suitable pigments there can be employed all coal-tar dyes as for example nitro compounds, azo dyes. oxy-quinones, xanthones, quinone-oxims, derivatives of triphenylcarbinol, quinone-imids, quiolins, acridins, phthaleins, azin compounds, ketone-imids, hydrazones, indulins, indigo, etc., and pigments derived from animal, vegetable and mineral sources also.
